In this article we will proceed to check of quantum computers structure i.e. qubits in different states by quantum theory principles and then we will express the qubits representation in different states by Bolch sphere in different aspects and we will achieve the density matrix and the expectation value in direction of z axis and finally we will proceed to collapse phenomena of quantum state in qubit measurement discussion.
